Recently, while I was at work, someone remotly logged into my computer with the name of "Administrator." They were going through my emails, trying to login to my bitcoin account, looking through as much as they could it seemed to try and steal my information. I caught them at the very end but they left a trail of websites they were trying to get in. Is there a way to secure my account?
I set up 2 factor auth, but that seems like it is only for logging into the application. I would like it for when I am connecting to any device in my list.
